Specification of Letters Patent.

Patented June 25', 1912.

Application filed July 30, 1910. Serial No. 574,701.

To all whom it may concern:

Be it known that I, CLAUD GOBELL, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Self-Tying Baling-Presses, of which the following is a specification.

This invention relates .to baling presses and has special reference to a wire banding and wire tying apparatus therefor.

One object of the invention is to improve and simplify the general construction of devices of this character.

A second object of the invention is to provide an improved trip mechanism to throw the banding and tying apparatus into operation when a bale has been completed.

A third object of the invention is to provide an improved twisting device for such an apparatus.

A fourth object of the invention is to provide an improved means to sever the wire and detach it from the twisting device.

With the above and other objects in view, as will. be hereinafter apparent, the invention consists in general of a Wire banding and wire tying apparatus of improved and novel character, said apparatus being adapted for use with a baling press of the plunger type.

The invention further consists of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically set forth in the claims.

In the accompanying drawings like characters of reference indicate like parts in the several views, and :Figure l is a plan View of a baling press equipped with this invention. Fig. 2 is a side elevation of such a press. Fig. 3 is a side elevation of the press taken from the side opposite to that shown in Fig. 2. Fig. 4 is a detail view of certain mechanism used in starting the apparatus, the view showing the mechanism detached from the press. Fig. 5 is a detail section on the line 5-5, of Fig. 1. Fig. 6 is a detail View of the twister showing the wire-cutter and the knock-off connected therewith. Fig. 7 is a view of the parts shown in Fig. 6 in a different position. Fig. 8 is a detail view showing certain parts of a trip operated clutch used in connection with this invention. Fig. 9 is a detail v1ew showing a wire holding mechanism used 1n connection with this invention. Fig. 10 is a section on the line 1010, Fig. 1.

In the present application there will be described and illustrated an apparatus having a double needle capable of carrying two wires while but one twisting device is shown and described, the one for the second wire being omitted in order to prevent confusion in the drawings. It will be understood, however, that the cutter and twister for the second wire is merely a duplication of the one shown connected thereto by ordinary sprocket gearing. It will also be understood that the number of wires may be increased at will by simply gearing an additional cutter and twister to the others, there being always one cutter and twister and one needle for each wire.

The press itself may be of any ordinary type wherein is provided a baling chamber 10 formed by a casing 11, a plunger 12, a power or driving wheel 13 and a pitman 14 connecting the driving wheel with the plunger 12. Furthermore the press is provided with the usual frame 15. Extending through the frame 15 is a shaft 16 whereon is mounted a pinion 17 meshing with the gear 13. This shaft 16 is also provided on its outer end with a gear 18 which meshes with a gear 19 revoluble on a shaft 20 extending transversely across the press. The shaft 20 projects well out from the press on the side adjacent the gear 19 and carried fixed on its end is a bevel gear 21 which meshes with a similar bevel gear 22 carried on a vertical shaft 23 mounted in a frame extension 24. On the gear 19 is carried a pair of diametrically disposed rollers 25.

The top of the baling chamber is provided with a slotted opening 26'and a shaft 27 extends transversely above this openihg, being supported in suitable bearings 28. On this shaft 27 is a toothed wheel 29 the periphery of which projects through the opening 26 into the chamber 10 so that as the bale is formed the wheel will be rotated and thus rotate the shaft. On this shaft is formed a crank 80 which projects over the side of the press.

At 31 is a lever which is pivoted intermediate its ends to the casing and is kept normally horizontal by means of a pair of balance springs 32 each having one end connected to one of the arms of the lever and the other end connected to a stud 33 located below the pivot of said lever. Pivoted adjacent the lever 31 is a bell crank lever having an arm 34 the end of which lies immediately below one end of the lever 31 the other end of said lever 31 lying in the path of the crank 30. The remaining arm 35 of the bell crank lever is connected by a link 36 with a latch 37 pivotally mounted on a latch bar 38 one end of which passes through a guide 39 carried by the press while the other end is connected by a link 40 with an extension 41 formed on the press. The end of the latch bar which passes through the guide is provided with a shoulder 42 and this end has one end of a spring 43 connected to it, the other end of said spring being connected to the guide 39. Pivoted to the frame is a trip 44 having one end normally held by the latch 37 the trip and latch being connected by a spring 45 in such manner that the trip when released from the latch will assume the position shown in dotted lines in Fig. 4. On the trip 44 is a projection 46 and on the wheel 13 is a coacting project-ion 47. Now while the bale is being completed the crank 30 will engage the lever 31 and move the same against the action of the springs 32. WVhen the bale is completed the crank will disengage from the lever and the springs 32 will cause the lever to fly violently back and strike the bell crank lever a sufficient blow to cause said bell crank lever to move through the link 36 the latch 37 and release the lever 44. The latter will assume the dotted line position of Fig. 4 and as the projection 47 moves around it will engage the projection 46 carried by the lever or trip 44 and rotate the lever 44 about its pivot. During the first part of such rotation the movement will cause the latch bar 38 to move through the guide against the action of the spring 43. \Vhen the movement has progressed sufliciently, the trip will be disengaged fromthe shoulder 42 by reason of the divergence of the paths of said shoulder and the end of the trip and the trip will resume its normal position. Meanwhile the rotation of the trip about its pivot will continue until the divergence of the paths of the projections 46 and 47 frees the latter from the former, this action taking place just after the trip has been again caught by the latch.

On the shaft 20 is an arm 48 pivoted to which is a species of pawl indicated at 49. This pawl has an offset portion 50 so positioned that the rotation of the pawl about its pivot brings the portion 50 into the path of the rollers 25 on the gear 19. This pawl is further provided with an arm 51 the extremity of which normally rests on a project-ion 52 formed on the link 40. Now when the latch bar is moved by the action of the member 47 as previously described, the

arm 51 will be released from engagement with the projection 52 and will drop. This will throw the projection 50 into the path of the rollers 25 and one of these rollers will engage said projection and rotate the arm 48 and consequently the shaft 20. When one revolution of the shaft has been nearly completed the arm 51 will strike the projection 52, the link 40 having meanwhile resumed its normal position, and the pawl 49 thereby be disengaged from a roller 25 of the wheel 19, thus causing a rotation once of the shaft 20 upon the completion of each bale.

On the shaft 23 is carried a plate 53 projecting from which is a crank pin 54 having a roller 55 mounted thereon. Extending from the press frame is a bracket 56 whereto is pivoted a lever 57 provided with a slot 58 in one end of which the roller 55 engages. Extending laterally from the press is a guide 59 wherein is mounted a needle frame 60 carrying a needle 61 pivoted to the frame and arranged to pass through suitable openings 62 formed in the press. This needle frame 60 is connected to the lever 57 by a link 63.

Now it will be seen that since the shaft 20 rotates once upon completion of a bale the shaft 23 will likewise rotate once and in consequence the needle will be reciprocated once through the chamber. This needle 61 is provided with an eye 64 wherein are mounted rollers 65, the latter being for the purpose of insuring the easy movement of wire through the eye. At 66 is a wire reel and the wire from this reel is led through the eye 64 of the needle. On the end of the shaft 20 opposite the parts just described is an interrupted or mutilated bevel gear 67 which is adapted to mesh during a certain portion of its revolution with a bevel gear 68 fixed on a shaft 69 mounted in suitable bearings 70 fixed to the side of the press. On this shaft 69 is fixed a gear 71. This gear 71 meshes with a gear 72 carried on a shaft 73 which is provided with a worm 74. This worm meshes with a worm wheel 75 on a shaft 76 carrying a pair of wire gripping disks 77. These disks rotate on each side of a member 78 so that when the end of a wire is engaged by the disks it will be so bent by the member 78 that it will be held from pulling loose from the said disks and member. These parts are so arranged that when the needle is projected through the baling chamber it will strike a deflector 79 which will bring the wire on the side of the needle toward the completed bale into engagement with the disks to be grasped by them and held so that the return of the needle will leave the wire extending through the chamber and the new bale will wire entirely around the bale. On the shaft 7 3 is also an interrupted gear 72' the teeth of which are adapted to mesh with a pinion 80 on a twister shaft 81 provided with a twister 82 so arranged that imme diately after the wire is gripped by the disks and member 78 the twister will operate to twist the two ends of the wire together. The twister is held from rotation until the wire is properly caught by the disks in the following manner. On the shaft 81 is a disk 83 having a notch 84 in its periphery. Pivoted to the press frame is an arm 85 carrying a pin 86 engageable in the notch 84 to prevent the rotation of the disk 83 and consequently of the twister. On the gear 72 is a lug 87 so arranged that just prior to the teethof the interrupted gear 72 engaging the pinion 80 the lug 87 will strike the arm 85 and lift the pin 86 out of the notch 84 thus leaving the twister free to rotate.

In order to provide for cutting off the wire and pushing the completed twist off the twister there is provided a lever 88 having an end 89 adapted to be engaged by a roller 90 carried on the gear 67, the ac tion of the roller being to temporarily depress this end of the lever 88 and then release it. To the other end of this lever 88 is connected a link 91 extending upwardly from the lever and having its upper end connected to a movable shear blade 92 coacting with a fixed shear blade 93, the wire between the twister and disks passing between said blades. The lever 88 also has a second link 94 connected thereto adjacent the link 91 and to this link is connected an arm 95 provided with a slot 96 working on a fixed pin 97. At 98 is a slide mounted for guided movement on pins 99. To this slide is pivoted a knock-off arm 100 and the arm is also pivoted to the slide. This part of the apparatus is so arranged that when the lever 88 rises at this end the knock-ofl arm will be both lifted and rotated on its pivot and move from the position shown in Fig. 6 to that shown in Fig. 7.

In order to hold the ear 68 in correct position to mesh with the interrupted gear when the latter rotates a stop mechanism is provided which comprises a disk 101 mounted on the shaft 69 and provided with a peripheral notch 102. At 103 is an arm which has one end hinged to the press frame and the other end provided with a roller 104 constantly urged against the periphery of the disk 101 by a spring 105.

The operation of the various parts of the device having been described in detail it is merely necessary to set forth that during the formation of a bale by the reciprocation of the plunger, the wire is carried around two sides and one end of the bale.

When the bale is completed the trip mechanism acts to throw the shaft 20 into operation and the rotation of this shaft successively reciprocates the needle, clamps the wire, twists the wire, cuts off the part around the bale, and pushes the completed twist off the twister leaving the parts ready for a succeeding bale.

In order to illustrate in general how the connections are made there has been shown in Figs. 2 and 5 a second apparatus A of this kind connected to that described by means of sprockets 106 carried on the respective shafts 7 6 and connected by a chain 107, and sprockets 108 carried by the twister shafts 83 and connected by a chain 109.
